Matrix 12800 Switchers • Installation
PRELIMINARY
o
Ethernet port — For systems consisting of a single switcher or for BME 0
on a multi-BME system, if desired connect the Matrix 12800 either directly
to an FPC 5000 Front Panel Controller or to an Ethernet LAN via this RJ-45
connector (figure 2-14). If you are connecting to a LAN, you can still use an
FPC 5000 as one of the other nodes of the LAN.

Cabling and RJ-45 connector wiring
It is vital that your Ethernet cables be the correct cables, and that they be properly
terminated with the correct pinout. Ethernet links use Category (CAT) 5e or CAT 6,
unshielded twisted pair (UTP) or shielded twisted pair (STP) cables, terminated
with RJ-45 connectors. Ethernet cables are limited to a length of 328 feet (100 m).
N
Do not use standard telephone cables. Telephone cables do not support Ethernet
or Fast Ethernet.
Do not stretch or bend cables. Transmission errors can occur.
The cable used depends on your network speed. The switcher supports both
10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet),
half-duplex and full-duplex, Ethernet connections.
• 10Base-TEthernetrequiresCAT3UTPorSTPcableatminimum.
• 100Base-TFastEthernetrequiresCAT5eUTPorSTPcableatminimum.
The Ethernet cable can be terminated as a straight-through cable or a
crossover cable and must be properly terminated for your application
(figure 2-15, on the next page).
• Crossover cable — Direct connection between the computer and the
matrix switcher.
• Patch (straight) cable — Connection of the matrix switcher to an Ethernet
LAN.
